aggiegold Posted October 15, 2021 Share Posted October 15, 2021 Dumb question I know, but I am looking at the rough country 3.5” lift, before I go all in, will I need to change the shocks? Here is the lift I’m thinking about: https://www.roughcountry.com/gm-suspension-lift-kit-29600.html?find=2020-gmc-sierra-1500-4wd-740563 Quote Link to comment Share on other sites More sharing options...

eppieguy Posted October 19, 2021 Share Posted October 19, 2021 I’m not sure but I’d assume you change your rear shocks, I put the rough country 3” on my 19 HC and the kit came with rear shocks. Quote Link to comment Share on other sites More sharing options...
Gangly Posted October 19, 2021 Share Posted October 19, 2021 It really depends on your vehicle. If you are starting off with a TB or AT4 and adding 3.5", you will definitely want a diff drop amongst other things. However, if you are taking a base 4x4 or Z71, you can do a 3.5" lift without a diff drop as it would basically be a TB or AT4 with a 1.5" additional lift which is doable. However, at that point I would suggest UCA's because of the geometry and extended TB CV's if you plan on doing any off road driving where you will be significantly flexing the suspension. Good luck with your setup, the anticipation and information gathering stage is often times as exciting as the install itself! Quote Link to comment Share on other sites More sharing options...
